Locations can be used in the configuration of IP Office systems to group extensions and systems by their physical location. This then allows the application of location specific settings.

For IP Office Select mode networks, the location settings can also be used to configure IP phone failover:

• The location entry in each system's configuration can specify a failover system. When set, extensions with the same location use that system for failover rather than the system line configured for Backs up my IP Phones.

• The failover system can be an expansion system. Expansion failover requires the addition of an IP Office line between the expansion systems.

• Location based resilience is supported on Avaya 1600 and 9600 series phones and all Avaya SIP endpoints.

• The location of an extension can be specifically set or can be determined from its IP address (unless routed through an ASBCE).
